People who lack emotional empathy
have to develop cognitive empathy instead if they want to functuion
properly in society. That includes a lot of learning: facial
expressions, gestures, tones of voice, etc. All the stuff empaths
understand instinctively. Local sociopaths teach their kids well. We
see little Rita here with her parents. Ren draws the pictures, Lara
explains them. Types of smiles were especially hard for her. Difference
between fake and real (Duchenne) smile is subtle. Another memory here
is 12 year old Tim who Rita's nurse at the time. Tim is not even a pure
empath, he's just close to that side of the empathic spectrum, yet he
impressed her enough that she began to question herself.
